The Orange line drops under the CSX line, it's just hard to see in the screenshot. Bear in mind I took that teaser screen shot last year. I have made a number of updates (i.e. CSX tk 7 was extended to Tower 1, the Boston Herald siding, the Green Lines mapped, etc) since then.

Great teaser there! I know you mentioned you have to complete the Orange Line north of North Station, but immediately south is the North Station crossover which I noticed was missing. Also, the Worcester Line west of Back Bay is oddly named "Washington St Tunnel" (that's the Orange Line from NEMC/Tufts MC to State Street).

Guys, quit over-analysing that screenshot. It was a work in process before I went to Boston way back in summer of 2009 to scout stuff out. I have 4 tracks at the Science Park portal now too (that Green line through downtown sure is screwy...). This is why I don't like to release stuff until I'm completely finished and have triple-checked everything.

Weird, I'm not sure how that Washington St labeling happened. What's the correct name of that tunnel?

Just to clarify: In Back Bay Station tracks 5 & 7 are numbered that way to avoid passenger cunfusion. Technically those tracks are CSXT tracks #1 & 2 respectively. CSXT ends at the eastbound signal of Cove Interlocking. From Cove Interlocking to Tower One they are tracks 5 & 7.

Okay this is all great stuff. I have looked over these maps and I have started to write my book, I was wondering if it would be okay if I could use any of these maps in my book? Also, from time to time, I will be glad to post sections of my book on here from you all that have helped me out so greatfully with the information, if you would check to see if I have any mistakes on any of the information wrong or what have you. Again this would be of great help.

Okay for the past few days, while listening to my scanner, I have been hearing the engineers say something about package to the world, and wallies world, I have also heard them say no d's, no changes. Could someone please enlighten me about what these mean? I just want to make sure that I understand what they mean before I put the wrong thing into my book. thanks again for everyone helping me out on the maps, You all are great help.
